The first thing that was coming into my mind was "He did not hesitate to use a lot of particle effects." I mean it in a positive way. But the game was to easy. I finished it in one or two minutes by rushing through.
So here some constructive criticism:
- Before the player is able to go to the next level, you need to defeat all enemies.
- The player movement was a bit stuttering. Did you use the movement in Update or FixedUpdate method?
- The projectiles of the enemies should be shootable.
But how does the game jam theme fit to your game?
